Used in combination with filers, applying tools and fabrics, epoxy is a multi-purpose gluing agent which is used for many construction and boat repairs. This material has gotten broad acceptance by professionals as well as laypersons, to accomplish a variety of projects. Also known as polyepoxide, the key applications of this gluing agent include: Covering or coating purposes: When applied in the form of a thin layer, epoxy resins seal the surface of the materials and organize the surface for polishing and strengthening sheets like, carbon fiber or fiberglass. Strong bonding: Polyepoxides are also used as a bonding agent in combination with some type of fillers to fill the space between two surfaces, and to fasten hardware with another. As a laminator: Epoxies are also used for lamination purposes, in order to create a rock-solid structure. Polyepoxide is used as a filler, to finely fill up the depressions in the wood or severely rotted wooden surfaces that can be sanded to provide the smooth surface. In addition to the aforementioned applications, Polyepoxides can also be used on various types of metals, fiberglass, carbon fiber, etc. How does epoxy work? Polyepoxide is a thermosetting polymer, which indicates that it is a bonding agent that cures. By nature, epoxy is a chemical substance that is easily responsive to other chemicals. One thing to be noted is that pure epoxy is more prone to reactions when it comes in contact with other chemicals. The other chemicals that are added to the epoxy acts as a hardening agent to result in the production of a strong adhesive. The basic formula of applying this chemical is that it must be a mixture of finely dissolved chemicals, such as polyepoxide and the hardening agent. During mixing, the compounds of polyepoxide react with the compounds of other chemicals. As a result, the chemical structure of the two mixtures changes and produces a considerably hard material. By using several types of slower or faster hardening chemicals to polyepoxide, the original chemical can change the time interval of the curing for epoxy. After the curing process, the chemical turns into a strong bonding agent that remains unaffected, even when it comes in contact with other chemicals and hard weather conditions. The main feature of the resultant product is that when applied between two layers, it properly settles into the pores of the surfaces and creates a bond that is extremely hard.
